NEW YORK, A CORPORATION OF NEW YORK PACKING CASE Application filed July 25,

Theobject of this invention is to provide a new and improved form of packing case made of paper products or more especially double faced corrugated board. Another object of the invention is to make the packing case with double walls, separated by cushion pads so that the cabinet or other contents of the packing case is practically suspended within the packing case so that it cannot be injured if the case is dropped on a corner, an edge or on the side.

This and other objects of the invention will be fully illustrated in the drawings, de scribed in the specificationand pointed out inthe claims at the end thereof.

Figure 1 is a perspective view of the packing case with the cover flaps turned back at the top exposing the interior, with the inner top wall omitted.

Figure 2 is a vertical section on the hue 2w-2m of Figure 1.

Figure 3 is a vertical section on the line 3w-3zv of Figure 1.

. Figure 4 is an enlarged perspective View of a portion of one of thecushion pads and the inner wall to which it is attached.

. In the drawings, like reference numerals indicate like parts. i

In the drawings, reference numeral 1 1ndica-tes a box made of paper products or preferably of double faced corrugated board n the ordinary way. On the top rim of this 'box are placed theflaps 2, 3, 4 and 5 which constitute the cover of the box. Thisbox can be varied at will to any of the standard forms of packing cases for it is old and constitutes no part of my invention. The wallsof this box are referred to as the outer walls of my improved packing case,

Inside of this packing case I provide the vertical walls 6, 7, 8 and 9. To the walls 7 and 9 are attached the horizontal cushion pads 10, 11, 12 and 13. These pads extend the full width of the walls 7 and 9, and from the wall6 to the wall 8, and completely fill the gap between the walls 7 and 9 which are the inner walls of the box andthe outer walls of the box adjacent thereto. On the walls 6 and 8 are provided the vertical cushion pads 14, 15, 16 and 17 which extend from near the 1928. Serial No. 295,307.

top to near the bottom of the box. These pads fill the gap between the inner walls 6 and 8 and the adjacent outer walls of the box adjacent thereto.

On the bottom of the box is placed the horizontal inner wall 18 which carries the cushion pads 19 and 20, which extend up into the box. This bottom wall 18 extends the full length of the box and extends under the inner walls 7 and 9 and extends only between and to the inner walls 6 and 8. The top wall 21 has the same dimensions as the bottom wall 18 and rests on top of the inner walls 7 and 9 and rests between the inner walls 6 and 8. This top wall 21 is provided with the horizontal cushion pads 22 and 23 which extend down into the box.

The horizontal cushion pads 19 and 20 at the bottom of the box and the horizontal cushion pads 22 and 23 at the project into the box, so to speak, so that the come directly into contact with the cabinet that is carried by the packing case. These pads are allmade short at one end as shown in Figure 2. That is, they come close to the wall 6 but are spaced at the end from the wall 8 so as to leave a gap between them and the wall 8, which gaps are adapted to receive the hinges of the doors on the front upright corners of the cabinet so that the hinges will not be subjected to any strain on the handling of the packing case with the cabinet in it.

The packing case is shipped knock down with the outer box folded up and the inner walls packed separately. When it is used in packing cabinets for shipment, the outer box isset up and the inner walls 8, 18 and 7 are placed therein in the order named. The wall 8 is first placed in position on its corresponding side of the box. The bottom wall is then put in place on the bottom against the wall 8 and the wall 7 is then put in place on the end with its lower end resting on the wall 18. The walls 7 and 8 are spaced from the outer walls by the cushion net is then placed in the packing case with the front of the cabinet toward the wall 8 and the top of the cabinet toward the wall 7. The walls 9 and 6 are then forced into the packing case in the order named. The top top of the box pads shown. The cabiwall 21 is then laid in place with the cushion pads22 and 23 restingon one end of the cabinet, the other end of the cabinet resting on 7 protect the CUShlOIl' pads 19 and 20 carried by the bottomwall 18. The flaps are thenclosed v and the'packing case is readyfor, shipment.

It'will' be understood that the topand front and the two ends of the cabinet are ghly fini he aend; Bo emi -r1 1- the ba and the bottomof the cabinet are ordinarily not finished or polished. It is therefore not the back and bottom. so

They also the polished surfacesvagainst' moisture making it unnecessary to wrap this cabinet inwax paper, itbeing understood thatno paper wrapping of anyjkind is necessary on the cabinet when it is packed with ithis case.

- A The cushi'on'padson [box are built up with p v double faced corrugated board all suitably glued together asis shown in Figure. 4fand I so that if' the outer box corner or-on an'edgeor on a side a portion 7 be crushed but the blow' willnot be communicated to the'cabinet' with,- rini Furthermore, the inner walls of the case are spaced apart {P0111 the outer walls and are'placed in relation't'o eachotlier so,
